Coolant bypass

Checking for leaks before I replace coolant. Can anyone confirm that the attached pic is of the bypass pipe? Thanks.

 

Check out post #9 for pictures.

That is the pipe, but I don’t see any leaks. Are you seeing pink areas on that pipe indicating coolant leaks?

 

No, I have not seen any pink deposits. I wanted to look around for leaks before drain and replace the coolant. Thanks for confirming.

 

Yep, you're looking at the top of the bypass pipe there. You can also stick your mirror/insoection camera up between the firewall and motor on the passenger side to check the underside.

 

I’ll look closer but haven’t seen any evidence of coolant leaks so far. Kind of surprised that Toyotavuses plastic here, but it is what it is. Thanks for the confirms and additional info.

 

Easy as pie to get to it! Five minute job to swap out! Oh…wait a minute I was dreaming Toyota in their great forethought stuck it half way down up against the firewall!

 

can you remove the carpet and cut an access hole?

 

Even if you could, probably not a great idea to be cutting extra holes in the firewall.

 

They couldn’t have placed it anywhere else…they could, however, have given us a metal pipe that didn’t break due to constant expansion and contraction from heat cycles. The pipe they used is complete crap as a choice for what it’s doing.

 

It’s best to get under the truck on the passenger side by the trans and look up with a flashlight. You’ll see dried pink stuff is you win the leaky pipe lotto. Ask me how I know… Once it gets bad enough those spots appear on the garage floor.

 

Yea, but how many engines have and external water crossover on the ass end! Ain’t smart in my opinion.

 

Tons of V engines do.

 

aluminum would have been a good choice.
